Description
Select the clock operating mode
These pins are multiplexed with the following pins.
MODE0: the IRL4 (INTC), FD4 (FLCTL), and PL4 (GPIO) pins
MODE1: the IRL5 (INTC), FD5 (FLCTL), and PL3 (GPIO) pins
MODE2: the IRL6 (INTC), FD6 (FLCTL), and PL2 (GPIO) pins
MODE3: the IRL7 (INTC), FD7 (FLCTL), and PL1 (GPIO) pins
MODE4: the SCIF3_TXD (SCIF channel 3), FCLE (FLCTL), and PN5
(GPIO) pins
Selects whether the crystal resonator is used
When MODE10 is set to the low level, the external clock is input from
the EXTAL pin.
When MODE10 is set to the high level, the crystal resonator is
connected directly to the EXTAL and XTAL pins.
MODE10 is multiplexed with the SCIF4_RXD (SCIF channel 4), FD2
(FLCTL), and PN1 (GPIO) pins.
Connected to a crystal resonator
Used to input an external clock or connected to a crystal resonator.
Used to output a local bus clock
The low level is output when the output clock of the CLKOUT is
unstable.
When the input to the PRESET pin is the low level, the high level is
output regardless of the status of the output clock on the CLKOUT
pin.
